The Pirates have seen a lot of players graduate from prospect status in the last year. Just during the 2017 season, Tyler Glasnow, Josh Bell, Trevor Williams, and Jose Osuna have graduated from prospect status. They join guys like Jameson Taillon, Adam Frazier, and Chad Kuhl from 2016. A few of those guys (Taillon, Bell, Glasnow) were at the top of the system, while the others have consistently ranked in the top 50 or top 30 prospects in the past.

Losing those players definitely provides a hit to the farm system rankings, although that's not really a bad thing. It doesn't hurt the Pirates that guys like Taillon and Bell are producing in the majors, and under control for five more seasons beyond 2017, instead of boosting their farm system rankings.

The challenge here is that the Pirates do need to continue having a strong farm system, as that means they will continue having a pipeline of talent coming to Pittsburgh in the future. Fortunately, they've maintained a strong farm system even after all of the promotions in the last year.

The disclaimer here is that the makeup of the system is a lot different. The system right now isn't as top-heavy as it was in the past, especially when Taillon, Bell, and Glasnow were part of the current prospect group. But the depth throughout the system is strong, and when putting the rankings together, we noticed a lot of depth in the middle of the system, with guys around the top 30 who would normally be in the top 20, and several guys outside the top 50 who could easily be on this list.

The lack of top-heavy talent may also be a short-term thing. The Pirates went heavy on prep players during the 2017 draft. They went heavy on prep pitchers in 2016. They also have a few international prospects who are showing promise in the lower levels. So while the top of the system is thinner now than in years past, there are a lot of options in the lower levels who can emerge in a few years to make up a new top-heavy system.

Below you will find our mid-season top 50 prospects for the Pirates' system. As usual, we separated the rankings into tiers, which I prefer over numerical rankings. The goal of the tiers is to give a better idea of talent, showing that there is a gap between the second and third best prospects, but not as much of a gap between the third and sixth best prospect. In some cases, such as tier 3, you could have a guy ranked as a top ten prospect by one person, and ranked outside of the top ten by someone else, with the difference coming down to personal preferences on floors, ceilings, and/or positional values.

Each player includes a link to the latest analysis on that player, with most of those articles coming in the last few weeks. This level of information is unparalleled by any other outlet.
